Missing "Link" option for polywav file in Fairlight?

I've got two tracks in a polywav file that I need to separate. In the past, I would right-click the track and deselect the "Link" option at the bottom of the context menu but this time it doesn't seem to exist. "Linked selection" is disabled but doesn't seem to affect this. This is in a multicam clip, but I've tried it directly in the timeline with the same result. Any idea what might have changed?

Change the Track format to Stereo from Adaptive 2.

It actually started out as stereo. I tried mono, stereo and adaptative 2 but all with the same result. I changed it back just now to be sure but there's still no "link" option.

Are multiple Audio Clips selected? The "Link Clips" option is not available for a single Clip selection.

Are you attempting to split channels to new Audio Tracks?
i.e. Convert to Link Group via the Track header contextual menu and then unlink?

Yes, exactly. For some reason I can't convert it to a linked group tho; the option is disabled.

Can you detail the source media format? Are you able to provide a sample of the source?
